/ Application filed July 15, 1926.. Serial No. 122,526.

Our invention relates to machines for dyeing yarn and particularly to the manner of supporting the yarn.

a'dye bath and thus dyed. It is a well known fact thatthe dye liquor becomes exhausted of its coloring matter as the warps pass through the bath. This exhaustion is effected by the aflinity of the coloring matter for the warp being dyed. An exhausted dye bath retains only a small percentage of its original coloring matter andthis amount makes the bath a noticeably lighter shade.

Due to this exhausted condition in dye baths, it is a diflicult problem to dye warps a uniform shade. The results obtainedby the present dyeing machines are that the end of the warp dyed first is of the proper shade and the end of the warp dyed last is of a noticeably lighter shade. .1 I

Dyed yarn of non-uniform shade. when worked. intov a fabric. especially knitted goods, causes streaks in thefabricthat is the chief cause of many second grade products.

An object of our invention is to provide a machine whereby warps of practically any length'may be dyed a uniform shade.

Another object is to provide means for re moving the supports from contact with the yarn at certain periods so that the dye liquor may more-readily and evenly impregnate the.

yarn. v s a l The drawings illustrate an embodimentof the invention andthe views therein'areas follows:' i f '1 Figure 1 is a .planview of a. dyeing machine showing an embodiment of .our inven: tion,

Referring to the drawings, 1 meanest In the art of dyeing, the yarn to be dyed is passed in groups, called warps,'througlr vat adapted to contain a-dyebath and a reel rotatable on the vat,,partly immersedin the bath and adapted to carryspaced layers of wound material through the dye bath.

The vat comprisesendmembers 3 and. a semi-cylindrical, trough 4. The edges ofthe trough fit in opposed semi-circulartgrooves a, 5 in end members 3 and are clamped mas grooves by tie rods6 which connect theend members. The vat thus formed may be lined with suitable noncorroding metallic lining 7. which would have nochemical efiTect on the dye bath. Each end memberB is provided with arecess 8 and a pair of guides?) extending upwardly from and aligned with the recess. These guides are adapted to guide the bearings of'the reel into the recesses when removing or 'replacing the reel. i f

The reel has a shaft 10 and end flanges 11 secured to the shafta short distance from its ends to provide trunnions 12 on which beam ing-blooks. 13 arerotatably mounted. These bearing blocks rest in recesses 8 and have their outer ends extending out of therecesses so that hooks or other means of connec tion may be applied for raising the reel out of the vat. y

[The warp to be dyed is wound in spaced layers, on bars 14 which are arranged in concentric series. The warp is first woundon the innermost series of bars, then on the next outer series and then on the third series and so onuntil alayer of warp iswoun d on each series of bars. JTo enablesuchwinding, the

bars are removably mounted in'flanges 11 of the reel. This mounting consists of bar supports 15, each havinga groove16 closed at its inner [end 17, and open at its outer end 18; and-blocks 19 on the ends of each bar 14 which fit in the'groove and abutea'ch other as shownin Figures Q-and 5. The blocks are heldin the grooves bynotches 20 in which the corners 21 of the" blocks engage. To cause the corners of the blocks to engage in thenotches,

the end faces 22 .are out so as to cause the block to tiltto one side. The. end facesso cut'makea blockthe shapeof arhomboid as shown in Figure 5. When the blocks abut each other in: the groove, the upper block keeps ,thenext lower block in position and its corner in the notch. f The uppermost block I a reel is lowered into the vat, gear teeth J31,"'on" bars are moved a short distance from the,

warp when immersed to the lowermost posil tion in the bath to allow the dye liquor to groove, will be raised to'move supports'15 thoroughly penetrate the warp. This is effected by mounting supports 15 in guideways to slideradially of the reel. Each support 15 is held in its guideway by a plate 26 secured to the back of thesupport and disposed at the outer side of the reel flange. Supports 15 at each end'of thereel have cam followers 27 which travel inja concentric groove28 in a cam plate 29." The cam plate at each end of the reel is fixed with'bearing block 13 and is thereby held against rotation. Asthe'reel rotates and moves followers'27 in the'g'roove 28, the followers when passing over the cam 30 at the lowermost part of the and bars 14 from the warp toward the center of the reel. This-allowsthe dye liquor to thoroughly penetrate those strands ofthe warp which were in contact with the bars.

Movement for rotating the reel is transmitted to gear teeth 31- on the periphery of flanges 11, from pinions 32 fixed on a drive shaft 33 rotatable inflbearings 34 mounted on the upper edge of end members 3 of, the vat. The drive shaft may be driven by any suitable driving means having avariable speed so that it may be varied for. dyeing different materials with different dyes. I

i In windingthe warp on the reel,spacing bars 14 are all removed except one bar of the innermost series. The endof the warp is ar then tied or otherwise fastened to this The other bars of this series are slipped into grooves 16 one by one as the reel is turned and.

each bar is held in position, with the corners 11 of its blocks in notches 20, by the warp wound thereon. The reel is turned untila layer of the warp is wound. on the full length of the series of bars. Another series of bars is then slipped into the grooves of supports 15 and alayer of warp is wound on that series in a similar manner. A third series of bars is then likewise slipped into the grooves of supports 15 and a layer of warp'is wound thereon and so on with the other series of bars until a.

layer is wound on each series, after which the end ofthe warp is tied to one ofthe'barsof the outermost series; The'reel is then raised and moved from its place of {winding and lowered into the vat with its bearing blocks 13 sliding between guides9 until they come'to rest in recesses 8 in end members 1. As the thelperipheries of "reel flanges 11','will"oome into mesh with pinions .32. The reel "isqthen rotated at the proper speed drives haft 33. During rotation the layers ,"of warp pass reel. p A dyeing machine including a vat; a reel mounted in the vat ;'bar supports mounted for through the dye bath in the vat and conbe moved upwardly from the warp-to allow the dye liquor to penetrate the warp contacting with the bars. After this point is passed the bars are returned to their original position to keep the warp tightly on the reel. At the end of the dyeing period, the dye bath will become partly exhausted ofits coloring matterwhich makes the bath of a lighter shade, The effect ofthe lighter shade dye liquor being the same on the entire warp, the entire warp will bedyed a uniform shade; Thereel is then raised by suitable raising mechanism,which is connected to the overhanging ends of the bearing blocks 13, and removed from the dye bath and lowered to a place for unwinding the warp from the reel. In unwindingflhe steps for winding are retraced; it beingunderstood that, if desired, a dyed warpmay be unwound from one reel and an undyed warp wound ona second reel While a warp is being'dyecl on a third reel.

Of course the dyeing machine illustrated is susceptible of various modifications and spaced bars carried by the supportsflipon which material tojbe dyed may be wound in concentric layers, and means for rotating the inward movement on the ends of the reel; bars removably mounted in the supports, upon which material" tobe dyed may be wound in concentric layers, and means for rotating the reel. v Y o "3.
